| `CollectPayload` | [`SignalWire.Relay.Calling.CallCollect`][signalwire-relay-calling-callcollect]     | Payload sent to Relay to collect input.       |

## Methods

### Stop

Stop the action immediately.

**Parameters**

*None*

**Returns**

[`SignalWire.Relay.Calling.StopResult`][signalwire-relay-calling-stopresult] - The result object to interact with.

**Examples**

> Ask user to enter a PIN and stop the action after 5 seconds.

```csharp
PromptAction actionPrompt = call.PromptTTSAsync(
    "Welcome to SignalWire! Please enter your PIN",
    new CallCollect
    {
        InitialTimeout = 10,
        Digits = new CallCollect.DigitsParams
        {
            Max = 4,
            DigitTimeout = 5,
        }
    });

Thread.Sleep(5000);

StopResult resultStop = actionPrompt.Stop();
```

### Volume

Change the volume of the action immediately.

**Parameters**

| Parameter | Type   | Required                                             | Description |
| --------- | ------ | ---------------------------------------------------- | ----------- |
| `volume`  | double | The volume from -40dB to +40dB where 0 is unchanged. |             |

**Returns**

[`SignalWire.Relay.Calling.PromptVolumeResult`][signalwire-relay-calling-promptvolumeresult] - The result object to interact with.

**Examples**

> Ask user to enter a PIN and change the volume after 1 second.

```csharp
PromptAction actionPrompt = call.PromptTTSAsync(
    "Welcome to SignalWire! Please enter your PIN",
    new CallCollect
    {
        InitialTimeout = 10,
        Digits = new CallCollect.DigitsParams
        {
            Max = 4,
            DigitTimeout = 5,
        }
    });

Thread.Sleep(1000);

actionPrompt.Volume(4.0);
```
